[0026] When needing to test, first, base plate 14 is placed on electronic scale 13, and lubricating oil is applied on base plate 14, to ensure that base plate 14 is in full contact with lubricating oil, then, electronic scale 13 and cylinder 6 are started by control box 4, the weight of base plate 14 is weighed by electronic scale 13, subsequently, the telescopic rod of cylinder 6 is retracted, so that sliding frame 8 moves downward along guide rail 7, whether the predetermined pressure value has been reached needs to be judged according to the numerical change on electronic scale 13, so that friction head 11 is pressed on the surface of base plate 14, then, servo motor 9 and torsion tester 12 are started, the output shaft of servo motor 9 rotates to drive connecting shaft 10 and friction head 11 to rotate, torsion tester 12 monitors the torsion on connecting shaft 10 in real time, and displays the monitored value on liquid crystal display 5 in real time, when lubricating oil gradually fails, the friction between friction head 11 and base plate 14 will increase accordingly, at this time, the value monitored by torsion tester 12 will also increase accordingly, in this process, the time from starting to rotate to lubricating oil failure needs to be recorded, if different types of lubricating oil need to be tested, only need to replace the type of lubricating oil applied on base plate 14, and repeat the above operation, if the same type of lubricating oil needs to be tested under different predetermined pressures, the pressure exerted by friction head 11 on base plate 14 can be adjusted by controlling the telescopic rod of cylinder 6 to retract, if the same type of lubricating oil needs to be tested on different materials, connecting shaft 10 in friction head 11 can be unscrewed, and friction head 11 of different materials is replaced, through the setting of cylinder 6, servo motor 9, torsion tester 12 and other equipment, the test system can conveniently realize the test requirements of different types of lubricating oil, the same type of lubricating oil under different predetermined pressures, and the same type of lubricating oil on different materials, so as to meet the diversified test requirements.
[0027] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 Four first guide rods 1401 are fixedly connected to the electronic scale 13. Two vertically aligned first guide rods 1401 are slidably provided with a pressing block 1402. A first elastic element 15 is sleeved on the first guide rod 1401. The two ends of the first elastic element 15 are respectively connected to the electronic scale 13 and the pressing block 1402. Two fixing plates 16 are fixedly connected to the electronic scale 13. Two second guide rods 17 are slidably provided on the fixing plates 16. Four top blocks 18 are slidably provided on the electronic scale 13. The pressing block 1402 can press the top blocks 18. One end of the second guide rod 17 is fixedly connected to the top block 18. A second elastic element 19 is sleeved on the second guide rod 17. The two ends of the second elastic element 19 are respectively connected to the fixing plate 16 and the top block 18. A rubber pad 28 is adhered to the top block 18.

[0028] Before placing the substrate 14, the pressing block 1402 is pushed downward to compress the first elastic member 15, so that the pressing block 1402 no longer presses the top block 18. The second elastic member 19 returns to its original state, causing the top block 18 to move outward. Then, the substrate 14 is placed between the multiple top blocks 18. Then, the pressing block 1402 is released, and the first elastic member 15 returns to its original state, pushing the pressing block 1402 to move upward and reset. The pressing block 1402 presses the top block 18 inward again, so that the top block 18 clamps and limits the substrate 14, thereby preventing the substrate 14 from moving during the test and affecting the test.
[0029] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8 A vent hood 20 is fixedly connected to the left side of the housing 1. The vent hood 20 has an air outlet slot 21. An air pump 22 is installed on the left side of the housing 1. Two air supply pipes 23 are connected to and communicate with the air pump 22. One end of the air supply pipe 23 is connected to the vent hood 20. An electric heating tube 24 is installed inside the vent hood 20. A temperature sensor 25 is installed on the rear side of the inside of the housing 1. A control knob 26 is rotatably installed on the control box 4. The air pump 22, the electric heating tube 24 and the temperature sensor 25 are all electrically connected to the control box 4.
[0030] Before testing, the electric heating tube 24 and air pump 22 are started by turning the control knob 26, and the ambient temperature required for the test is set. The air pump 22 runs and draws outside air into the air guide hood 20 through the air supply pipe 23. At this time, the electric heating tube 24 heats the air in the air guide hood 20 according to the set value. The heated air is dispersed in the chamber 1 through the air outlet 21, so that the inside of the chamber 1 maintains a constant test temperature and reduces test error. During this process, the temperature sensor 25 monitors the temperature inside the chamber 1 in real time.
